Description:The main purpose of this book is to explain certain physical considerations useful not only to a beginner learning how to play a musical instrument, but also to an accomplished musician trying to gain full technical mastery of an instrument. Some conscious understanding of the facts of physics and physiology, while obviously not necessary, can speed up the learning process for a beginner and may help the good performer to acquire a level of technical skill, accuracy, and endurance unlikely ever to be attained otherwise.
